Adsorption studies were conducted to determine whether adsorbent concentration (soil-solution ratio) affected insecticide adsorption by soils and clays. Adsorption isotherms were obtained for several insecticides in Bondhead sandy loam and Ca-saturated illite suspensions using adsorbent concentrations that were varied over several orders of magnitude. There was no evidence that altering adsorbe...

Wastewaters obtained from fenvalerate manufacturing process were treated for its safe disposal using activated coconut shell carbon (acc) as adsorbent. In this work, the removal efficiency of organic matter in terms of chemical oxygen demand (COD) utilizing acc has been investigated. Various parameters which can influence the adsorption like adsorbent dosage, contact time of solution with adsor...

This investigation focuses on the effectiveness of coconut shell activated carbon in removing synthetic dye mixture from aqueous solutions. Coconut carbon, an economical and effective adsorbent, was made agricultural waste raw material chemically by sulphuric acid treatment. Activated is characterised using FT-IR SEM analysis. Batch adsorption studies were conducted adjusting conditions such co...

Activated carbon prepared from coir pith using ZnCl2 was investigated to find the feasibility of its application for removal of 2,4,6-trichlorophenol (TCP) in aqueous solution through adsorption process. Batch mode kinetics and isotherm studies were carried out to evaluate the effects of contact time, initial concentration, adsorbent dose, pH, and temperature. Lagergren, second order, and Bangh...

BACKGROUND/AIMS Cytokines play important roles in the pathophysiology of systemic inflammatory response syndrome (SIRS) and sepsis. Therefore, some effective measures to remove cytokines from the bloodstream could be effective in the treatment of SIRS and sepsis. The aim of this study was to evaluate the cytokine adsorptive property of various adsorbents for the purpose of the development of ne...

A highly selective ligand exchange type adsorbent was developed for the removal of trace arsenic(V) (As(V)) and phosphate from water. This adsorbent was prepared by loading zirconium(IV) on monophosphonic acid resin. This adsorbent was able to remove toxic anions efficiently at wide pH ranges. However, low pH was preferable for maximum breakthrough capacity in an adsorption operation. The effec...

In some part of the world, groundwater source can become unsafe for drinking due to the high concentration of fluoride ions [1]. The low cost and facile-produced adsorbent like palm stone could effectively removed fluoride ions through adsorption process. In this dataset, the influence of fluoride ion concentration, solution pH, adsorbent dosage, and contact time on fluoride ion adsorption by p...

Removal of cadmium from aqueous solution was studied; using platanus orientalis leaves (POL) and their ash in 2006 in Iran. Bach adsorption experiments were performed as a function of solute concentration, contact time, pH and ironic strength for the experiment. The effect of Ca , Mg , Na and K on adsorption was 2+ 2+ + then examined. The effect of this adsorbent on COD in aqueous solution show...

The aim of this study was to examine the use of polyamide 6 nanofibers as an adsorbent material for removal of dye on textile wastewater. Simulated wastewater of acid dye (namely Color Index Acid blue 41) was used for experiment test with concentration of 0.01, 0.02 and 0.03g/L. Two kinds of electrospun polyamide 6 nanofibrous membranes with weight per unit area respectively 1.0 and 2.9g/m2 wer...
